Abstract

An embodiment of the present application provides a TACAN signal detection method, device, and storage medium, wherein the method includes: acquiring a signal to be tested; determining the autocorrelation energy of the signal to be tested and the correlation between the signal to be tested and a reference signal Cross-correlation energy; the reference signal is a signal that is the same or similar to the Tacan signal envelope; when the cross-correlation energy is greater than the autocorrelation energy, determine the pulse characteristic parameter of the signal to be measured; judge the pulse characteristic parameter Whether it meets the characteristic requirements of the Tacan signal; if yes, it is determined that the signal to be tested is a Tacan signal. The Tacan signal detection method, device, and storage medium provided in the embodiments of the present application can solve the problems in the prior art that the accuracy of signal detection is low and the detection process is relatively complicated.

Description

technical field [0001] The present application relates to a signal detection method, in particular to a Tacan signal detection method, device and storage medium. Background technique [0002] Tacan (abbreviation: TACAN) signal is a short-range radio navigation system, which provides two-dimensional positioning of azimuth and distance for aircraft within a coverage radius of 350km on the 1000 MHz frequency band, and it has high precision, small size, and easy installation At present, it is widely used in many countries such as the United States and NATO. It is mainly used for route navigation, aerial refueling and air formation flight. Therefore, the detection of TACAN signals and the analysis of its signal characteristics have important application significance for enriching detection methods and improving detection performance. . [0003] At present, the commonly used method of TACAN detection uses a fixed threshold to detect the signal, and detects the TACAN signal throug...
